Black Hole --Rabbits have commandeered this post!--

Weeee! We finally got a hold of the computer! Hmm, what to post? It looks like the dog was going to write about black holes? Haha, how funny! Black holes aren't real, are they? Silly dog. We should play Parcheesi! Or, even better, make up rules on how black holes work. Won't that be fun?

Hmm, so we don't know what black holes are, so we'll have to make them up. Think of a black hole like a cartoon hole that you can place anywhere:

This is what a black hole is, a small flat portable hole you can carry in your pocket. Dashedly useful for when your caught cheating in Parcheesi, wot wot?

*All right, bunnies go back to your game! Silly wabbits!*

*Ahem* As I was saying, black holes are nothing at all like that. They have to do with gravity, and are often super massive. What's more, they wouldn't fit in your pocket. :P  A black hole is a region of space-time where gravity is so strong that nothing, not even light can escape. As a special treat, I've invited Shadow, a small black cat with extra-ordinary knowledge of black holes, to share what he knows.

Good Morning everyone. My name is Shadow. I've spent a lot of time traveling with Schwarzschild the mouse. He first introduced me to the theory of wormholes and black holes. Since then, I have been investigating in my own quiet way, the subject of black holes. As Sheepdog stated, they have a massive gravitational pull, which sucks everything around it into its center. The point where objects first begin to be pulled, and cannot escape is called the event horizon. Remember that term, I'll use it later. Anyways, this theory was first considered in the 18th century by a pair of outrageous squirrels by the name of Michell and Laplace. Their work was expanded by my friend the mouse. He really is quite bright! Black holes are what I call an observable enigma, they actually exist according to our top scientists. For example, they theorize a super-massive black hole is at the center of our galaxy, keeping all the stars rotating around it in orbit. Another fascinating feature of black holes, is even though they are by all accounts invisible, any particles including light will accelerate as they approach the black hole, giving off a blinding light until they are swallowed up. This light surrounding the black hole is perhaps the brightest objects in the universe. The center of a black hole, also called the singularity is theorized to have infinite density. Any object sucked in is compressed, and added to the total mass of the black hole. Black holes can be formed through the collapse of a star, or other giant object. Once formed, black holes were originally though to last indefinitely. 

However, a recent discovery by a very intelligent hawk by the name of Stephan showed that black holes emit a kind of radiation. In short, it releases certain particles while gobbling up all other particles. If the black hole has not other particles to swallow, it will eventually release enough hawking particles that it will evaporate. A small black hole the size of a car would evaporate in an instant due to this radiation. A black hole the size of a star would take significantly longer. 

Thanks Shadow. Sorry about the rabbits...

No worries. If the lesson is over for the day, I may go join them actually. A cup of cocoa sounds pretty good.

Silly wabbits. We need some sheep dog posts about the rabbits' escapades during the holidays. However, this might not happen until *after* the holidays, as sheep dog's services will be required to keep all the rabbits in line! Merry Christmas to Sheep Dog!
